Labor Costs: $2,000 to $4,000 if hiring a professional mechanic

For a high-performance build, the cost can rise to $15,000 or more, especially if you’re upgrading the engine for extreme horsepower.

Can I swap a 2JZ into any car?

While it is technically possible to swap a 2JZ engine into almost any car, compatibility is a key factor to ensure a successful and efficient swap. Some cars are naturally better suited for the 2JZ engine due to factors like:

Engine bay space (whether the 2JZ engine will physically fit).
Transmission compatibility (whether the car’s existing transmission can work with the 2JZ engine or needs custom adapters).
Aftermarket support (whether there are parts and kits available for the swap).

Cars like the Toyota Supra, Nissan Silvia, and Lexus IS300 are among the best for a 2JZ swap due to their strong compatibility and available aftermarket solutions.

What is the easiest car for a 2JZ swap?

The Toyota Supra MKIII (also known as the A70 Supra) is often considered the easiest car for a 2JZ swap. Since it was designed for the 2JZ engine from the start, it offers natural compatibility with the 2JZ-GTE and 2JZ-GE engines. Additionally, the Supra has strong aftermarket support and an established history of successful swaps.

Other relatively easy platforms include the Nissan Silvia (S13, S14, S15) and BMW E36, which also have robust aftermarket support and are popular among tuners.

What modifications are required for a 2JZ swap?

Swapping a 2JZ engine into a car typically requires several key modifications to ensure that the engine fits and functions correctly. Some of the most common modifications include:

Engine Mounts: Custom or aftermarket mounts may be needed to secure the engine in place, especially if the car was not originally designed for the 2JZ engine.
Wiring and ECU: The stock wiring harness may not be compatible with the 2JZ engine, requiring custom wiring or the use of a stand-alone ECU.
Cooling System: The stock radiator and intercooler may need to be upgraded to handle the increased power of the 2JZ engine.
Fuel System: Depending on the setup, you may need to upgrade the fuel pump, injectors, and lines to ensure the engine receives adequate fuel.
Exhaust System: A custom exhaust system may be necessary to accommodate the 2JZ engine and turbo components.

These modifications will depend on the car you are working on and the specific type of 2JZ engine you choose to install.
